‘Index service’ holds index trees, which may require different sharding than docs. Index service is mostly about IO, partitioning pre-calculated data records. ‘Query service’ runs queries, which may involve fetching index, complex sub-querying, filtering, grouping, etc. Something like view + _list call in CouchDB, often CPU-bound, so sharding is more about load balancing than data partitioning. ermouth вт, 19 нояб. 2019 г. в 22:53, Nick Vatamaniuc <vatam...@gmail.com>: > > Isn’t it an approach used by Couchbase? > https://docs.couchbase.com/server/current/clustersetup/services-mds.html > > Thanks for the link.
